RADIANT GAS HEATER.

Application filed July 26,

To all whom it may concern Be it known that we, \VILLIAM W. HonLowar and HENRY KIELBERG, citizens of the lnited States of America, and resldents, respectively, of \Vheeling, county of Oh1o, and State of West Virginia, and Martins Ferry, county of Belmont, and State of- OlllO, have invented certain new and useful Improvements in Radiant Gas Heaters, of whlch the following is, a specification.

This invention relates broadly to gas heaters of the radiant type, and more particularly to a sheet-metal heating stove of that character in which tubular radiants of earthen composition are employed.

The primary object of the invent on 15 to provide an efficient o en-front radlant gas heater composed whol y of sheet metal and possessing a construction which is strong, rigid and durable and which may be manufactured at relatively small cost.

A still further object is to provide a stove or heater of the character referred to having a form and construction which adapts it to be snugly packed for storage and sh pment in partially knocked-down form 1n individual corrugated paper or cardboard cartons of ordinary rectangular form wlth its detached parts closely nested within and protected against injury by the lower part of the heater casing.

With these and other important objects in view, the invention resides in the features of construction, arrangement of parts and combinations of elements which will hereinafter be fully described, reference being had to the accompanying drawings, in which- Figure 1 is a top plan view of a stove or heater constructed in accordance with our invention;

Figure 2 is a vertical section of the same;

Figure 3 is a horizontal section on line 3-3, Fig. 2;

Figure 4'is a front elevation of the onepiece stove casing;

, Figure 5 is a view of said casing partially in top plan and partially in horizontal section; and- Figure 6 is a section on line 66, Fig. 4.

. Referring to said drawings,'- indicates the rear wall and 2 the side walls of a stove casing of substantially rectangular form in horizontal section, said casing being herein 1922. Serial No. 577,722.

shown as formed a single piece of sheet metal. A n outwardly pressed terminal bead or roll 3 is formed on the lower edge of the rear wall 1, and similar beads or rolls 4 are formed on the lower edges of the side walls 2, said rolls being designed to receive in clamping relation thereto the panels 5 and 6 of reinforcing devices constituting a substructure which is disclosed in our compan- 1on application for Letters Patent, Serial No. 577,726, and which serve as mountings for legs 7 and 8 whcrebythe stove is supported.

The front edge portions of the side walls 2- are turned inward at right angles, forming panel-like facings 9 which present the appearance of corner posts, said facings havingrearwardly directed terminal flanges 10 to which are bolted or otherwise attached the front edges of divergently inclined shields or plates 11 which occupy positions in suitably spaced relation to the side walls, said plate serving to shield said side walls and to provide an intermediate space forthe circulation of air. Said plates 11 are disposed upright and have their lower edges shaped to conformably seat upon a horizontal sheetmetal plate 12 which constitutes a support for a plurality of alined'radiant tubes 13, and upon a fender plate 14 which has its rear edge mounted upon an inclined flange 12 of said radiant support and its front edge seated upon the horizontal ledge 15 formed by an inturned flange provided on the upper edge of a low sheet-metal cross panel 15 which joins the corner posts 9 adj acent to the lower ends of the latter. Said parts 12 and 15 are best illustrated in Fig. 2, which shows a sectional view taken substantially on line 2-2, Fig. 3.

An inturned terminal flange 1 is formed on the upper edge of the rear wall 1, and similar flanges 2 and 9 are formed on the upper edges of the side walls 2 and posts 9, respectively. Seated upon said terminal flanges is a top plate or pover 16 which is pressed upwardly adjacent to its rear edge portion to form an upstanding roll-like rib 16". The rear edge of said cover is bent forward beneath said rib 16 and is then bent back upon itself in clamp-like formfor closely embracing the'flange 1 of the rear wall 1. Said cover has an approximate U- shape in top plan, being designed to overlie that portion of the casing interior located rearward of the fender plate 14 and to overlie and close the spaces between the side walls 2 and the shield plates 11, while leaving open the space in front of the radiants 13.

A downturned flange 16 formed upon the front edge of the cover complements a vertical transverse depending flange 17 for shielding from view that portion of the casing interior located at and above the levelof the upper ends of the radiants. Said flange 17 is formed upon the front edge portion of a horizontal p ed upon the upper edge portion ofan upright sheet metal back wall 18. Said back wall is located at a suitably spaced distance rearward of the radiants 13, belng seated upon the radiant support 12-, and has a forwardly pressed rib 18 agalnst wh ch the backs of the upper end portions of said rad ants rest. The upper end of the back wall 1s turned rearward to form a horizontal leg 18 which is suitably attached to the rear wall 1 of the casing.

Located rearward of said back wall 18 1s a suitably inclined plate or deflector 19 whereby heat radiated rearward by said back wall is deflected away from the rear casing wall. The upper and lower edge portions tween the shield plates 11 and the side walls 2, whence it escapes through suitable apertures or perforations 20 provided in the rlb portion of the cover 16. To facilitate circulation of air for carrying the heat from said space between the deflector and the rear casing wall, draft openings or perforations 21 are provided in the lower leg 19 of the deflector and other perforations 22 are provided in the rear portion of the radiant support 12.

Likewise heat between the deflector '19 and the back wall 18 finds its way to the spaces between the shield plates 11 and the end walls 2 and thence escapes through said apertures 20. Circulation for removing such heat is facilitated by the perforations 22 of the radiant support and also by the provision of perforations 23 in the leg 18 of the back wall 18.

The portions of the cover 16 which overlie the post-like or boxing-like front corners of the stove casing are preferably surmounted by knobs 24 designed to give the structure an ornamentally finished appearance.

A burner 25 is supported beneath the radiant support 12, the same being designed to furnish a readily combustible mixture of gas and air to the radiants 13 through aper ate 17 which is mount tures 26 provided in said support and em braced by thebase portions of said radiants.

From the foregoing description it will be understood that we have devised a sheetmetal heater of open-frontradiant type having a construction not only affording great strength, rigidity and durability, but also providing for ready and convenient assembling of parts. Furthermore, it will be apparent that, due to the fact that it is composed almost wholly of parts formed of sheet metal, it is relatively inexpensive to manufacture.

The heater structure described is adapted to be partially knocked down and packed for storage and shipment in individual cartons of ordinary rectangular form. The legs 7 and 8 have only to be removed to render the heater structure of substantially rectangular form for snugly fitting such a box or carton. and these legs, together with the individually wrapped radiants, may obviously be wrapped and stored within the casing either in the open space located in front of the back wall or that beneath the radiant support.
